Abstract :Aim: Temporomandibular joint disorder(TMD) present symptoms such as pain, swelling, clicking or crepitating sounds, limitations or blockages in jaw movements, and may even affect simple functions such as eating and speaking. This study aims to evaluate the impact of disc displacement type on jaw function in patients with TMD who suffer from disc displacement. Material and Methods: This cohort study was conducted on patients who had disc displacement in the temporomandibular joint. The independent variable was the type of disc displacement. The outcome variable was the Jaw Functional Limitation Scale-20(JFLS-20) scores. The covariates were the patient\'s age and pain score. Results: The study groups were formed by including 72 patients with disc displacement, while the control group was formed by including 28 healthy volunteers. The control group had lower JFLS-20 scores than the disc displacement groups(p<0,05). Although there was no statistically significant difference in JLFS-20 scores between the disc displacement groups, disc displacement with reduction group had significantly lower pain scores than both disc displacement without reduction groups(p<0,05). Conclusion: It was observed that individuals with disc displacement experience restricted jaw functions, and this limitation is not affected differently by the various subtypes of disc displacement.
